[Solved] How to Expand and Collapse Nested RadGrid

[Anantharaman]

Hi,

How do I collapse and expand the nested rad grid on click of the radio button onselectedindex change of the MasterGrid view of every row.
For the same I have the radio button onselectindexchange event associated in every row of the MasterGrid and find the child nested grid to bind. The Issue is that I am able to find the child grid and bind it but the child grid is not expanding and collapsing after bind.

Quick response appreciated !

Hi,

Try the following.
C#:

protected void RadioButton1_CheckedChanged(object sender, EventArgs e)
  {
      RadioButton radio = (RadioButton)sender;
      GridDataItem dataItem = (GridDataItem)radio.NamingContainer;
    GridTableView tablview = (GridTableView)(dataItem).ChildItem.NestedTableViews[0];
     foreach (GridDataItem item in tablview.Items)
     {
         item.Expanded = true ;
         tablview.Rebind();
     }
 }

Thanks,
Shinu
